What is the impact of kelp forest density and/or area on fisheries?
(Journal article; Peer reviewed, 2013)Kelp forests are highly productive ecosystem engineers of rocky cold-water marine coastlines, providing shelter, habitat and food for a variety of associated organisms. Several factors have been related with an observed ... -
Climate warming feedback from mountain birch forest expansion: Reduced albedo dominates carbon uptake
(Journal article; Peer reviewed, 2013)Expanding high elevation and high latitude forest has contrasting climate feedbacks through carbon sequestration (cooling) and reduced surface reflectance (warming), which are yet poorly quantified. Here, we present an ... -

Membrane bioreactors (MBRs): Activated sludge filterability and full-scale MBR functioning
(Journal article; Peer reviewed, 2013)Despite continuous developments in the field of MBR technology, membrane fouling together with the associated energy demand and related costs issues remain major challenges. The efficiency of the filtration process in an ... -
CO2 increases C-14 primary production in an Arctic plankton community
(Journal article; Peer reviewed, 2013)Responses to ocean acidification in plankton communities were studied during a CO2-enrichment experiment in the Arctic Ocean, accomplished from June to July 2010 in Kongsfjorden, Svalbard (78°56′ 2′′ N, 11°53′ 6′′ E). ... -
Contrasting responses of DMS and DMSP to ocean acidification in Arctic waters
(Journal article; Peer reviewed, 2013)Increasing atmospheric CO2 is decreasing ocean pH most rapidly in colder regions such as the Arctic. As a component of the EPOCA (European Project on Ocean Acidification) pelagic mesocosm experiment off Spitzbergen in 2010, ... -
«Gigant-mikroben» sjøplomme Nostoc pruniforme i Slettnes naturreservat på Nordkinnhalvøya, Finnmark
(Journal article; Peer reviewed, 2013)This article is the first comprehensive account about the occurrence of the cyanobacterium Nostoc pruniforme in Norway. The investigation was carried out in a rocky pool inhabited by the species. The locality is situated ... -
Kan informasjon om bløtbunnssamfunn og modeller for geofysiske forhold gi heldekkende kart over naturtilstanden i norske kystvann?
(Journal article; Peer reviewed, 2013)Artsmangfold og sammensetning av dyr i marine sedimenter (bløtbunnsfauna) er spesielt egnet for å måle miljøets tilstand, fordi ulike typer partikkelbundet forurensning før eller senere når havbunnen. Indekser på artsmangfold ... -
Effect of water treatment on the growth potential of Vibrio cholerae and Vibrio parahaemolyticus in seawater
(Journal article; Peer reviewed, 2013)In laboratory experiments we added Vibrio cholerae and Vibrio parahaemolyticus to bottles with seawater previously treated by filtration, UV, chlorine or ozone. The purpose was to investigate the influence of different ... -

Faunal trophic structure at hydrothermal vents on the southern Mohn's Ridge, Arctic Ocean
(Journal article; Peer reviewed, 2013)We explore the trophic ecology of heterotrophic fauna associated with a high temperature (HT) vent, 2 low temperature vents, a ‘near-HT vent’ habitat and a non-vent site situated at upper bathyal depths on the southern ... -
Combined and interactive effects of global climate change and toxicants on populations and communities
(Journal article; Peer reviewed, 2013)Increased temperature and other environmental effects of global climate change (GCC) have documented impacts on many species (e.g., polar bears, amphibians, coral reefs) as well as on ecosystem processes and species ... -
